LPOP to remove and return elements from the head of a list.
Without a count a single element is returned, or null when the key does not exist. With a count, up to that many elements are removed and returned in the order they were popped, and the reply is an empty array or null when the list is empty. The key is deleted once the last element is removed.
Paired with RPUSH this gives a first-in, first-out queue; paired with LPUSH it gives a stack. Use BLPOP when a consumer should wait for work rather than poll.
Syntax
Arguments
Response
The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.
Examples
TCP examples use the TLSREDIS_URL from the Upstash console. REST examples use UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN.
